Ishushu V , okanye i-V Hot - ivakala ngcono ngesiNgesi, ngokungathandabuzekiyo - yayiligama eliye lafumana ukubonakala emva kokuqaliswa kwe-Mercedes-AMG GT, exhotywe nge-M178, i-4000cc twin-turbo V8 enamandla onke avela e-Affalterbach.
Kodwa kutheni Hot V? Ayinanto yakwenza nezichazi zeempawu zenjini, kusetyenziswa intetho yesiNgesi. Enyanisweni, isalathiso kwinkalo ethile yokwakhiwa kweenjini nge-V-cylinder - nokuba i-petroli okanye idizili - apho, ngokungafaniyo nesiqhelo kwezinye iiVs, izibuko zokukhupha (kwintloko ye-injini) zikhomba ngaphakathi i-V endaweni yangaphandle, evumela ukubeka i-turbocharger phakathi kweebhanki ezimbini ze-cylinder kwaye kungekhona ngaphandle kwazo.
Kutheni usebenzisa esi sisombululo? Kukho izizathu ezithathu ezilungileyo kakhulu kwaye makhe sifikelele kuzo ngokweenkcukacha ezithe vetshe.
Ubushushu
Uya kubona apho igama elithi Hot livela khona. I-Turbocharger inikwe amandla yigesi yokukhupha, kuxhomekeke kuzo ukuba zijikeleze ngokufanelekileyo. Iigesi eziphumayo zifuna ukuba shushu kakhulu - ubushushu obuninzi, uxinzelelo ngakumbi, ngoko ke, isantya esiphezulu -; le kuphela kwendlela yokuqinisekisa ukuba i-iturbine ngokukhawuleza ifikelela kwisantya sayo sokujikeleza.
Ukuba iigesi ziyaphola, zilahlekelwe luxinzelelo, ukusebenza kakuhle kwe-turbo kuncitshisiwe, nokuba kukwandisa ixesha de i-turbo ijikeleze ngokufanelekileyo, okanye isilele ukufikelela kwesona santya siphezulu sokujikeleza. Ngamanye amazwi, sifuna ukubeka i-turbos kwiindawo ezishushu kwaye kufuphi ne-exhaust port.
Kwaye kunye nezibuko zokukhupha ezibhekiselele ngaphakathi kwe-V, kunye ne-turbos ebekwe phakathi kweebhanki ezimbini ze-cylinder, zikhona nakwi "indawo eshushu", oko kukuthi, kwindawo ye-injini ekhupha ubushushu obuninzi kwaye isondele kakhulu iingcango zokukhupha umbhobho - obangela ukuba imibhobho embalwa ithwale iigesi zokukhupha, kwaye ngoko ke ilahleko encinci yobushushu xa uhamba ngayo.
Kwakhona abaguquli be-catalytic babekwe ngaphakathi kwe-V, endaweni yendawo yabo yesiqhelo phantsi kwemoto, njengoko ezi zisebenza kakuhle xa zishushu ngokwenene.
Ukupakishwa
Njengoko unokucinga, ngayo yonke loo ndawo ithathwe ngokufanelekileyo, yenza i-twin-turbo V injini ixinene ngakumbi kunenye ene-turbos ebekwe ngaphandle kwe-V . Njengoko ixinene ngakumbi, kulula ukuyibeka kwinani elikhulu leemodeli. Ukuthatha i-M178 ye-Mercedes-AMG GT, sinokufumana iindidi zayo - i-M176 kunye ne-M177 - kwiimodeli ezininzi, nakwi-C-Class encinci.
Enye inzuzo kulawulo lwe-injini ngokwayo ngaphakathi kwendawo elungiselelwe yona. Izihlwele zigxile kakhulu, nto leyo eyenza ukuba iijingi zabo ziqikeleleke ngakumbi.
Eyokuqala eshushu iV
I-Mercedes-AMG yenza igama le-Hot V lidume, kodwa babengengabokuqala ukusebenzisa esi sisombululo. Imbangi yayo i-BMW yayikhe yaqala kwiminyaka eyadlulayo - yaba yeyokuqala ukusebenzisa esi sisombululo kwimoto yokuvelisa. Injini ye-N63, i-twin-turbo V8, yavela ngo-2008 kwi-BMW X6 xDrive50i, kwaye yayiza kuxhobisa ii-BMW ezininzi kuquka i-X5M, i-X6M okanye i-M5, apho u-N63 waba yi-S63, emva kokudlula ezandleni zika-M. Kodwa lo Ubeko lwe-turbos ngaphakathi kwe-V lwaqala ukubonwa kukhuphiswano, kwaye ke kwiklasi yenkulumbuso, i-Formula 1, ngo-1981. I-Ferrari 126C yaba yeyokuqala ukwamkela esi sisombululo. Imoto yayixhotyiswe nge-V6 kwi-120º ene-turbos ezimbini kunye ne-1.5 l kuphela, ekwazi ukuhambisa ngaphezu kwe-570 hp.
Ulawulo lweTurbocharger
Ukuba kufutshane kwee-turbocharger kumazibuko wokukhupha, kukwavumela ulawulo oluchanekileyo kwezi. Ii-injini ze-V zinolandelelwano lwazo lokutshisa, okwenza ukulawula i-turbocharger kube nzima ngakumbi, njengoko i-rotor ilahlekelwa kwaye izuza isantya ngokungaqhelekanga.
Kwi-injini ye-twin-turbo yesiqhelo ye-V, ukuthoba olu phawu, ukwenza isantya sokutshintsha sicingelwe ngakumbi, kufuna ukongezwa kwemibhobho engaphezulu. Kwi-Hot V, kwelinye icala, ibhalansi phakathi kwe-injini kunye ne-turbos ingcono, ngenxa yokusondela kwawo onke amacandelo, okukhokelela kwimpendulo ye-throttle echanekileyo kwaye ebukhali, ebonakala kulawulo lwemoto.
I-Hot Vs, ke ngoko, ilinyathelo eliqinisekileyo eliya kwi-turbos "engabonakaliyo", oko kukuthi, siya kufikelela kwinqanaba apho umahluko kwi-incisive response kunye nomgca phakathi kwe-injini yendalo enqwenelekayo kunye ne-turbocharged iya kuba yinto engabonakaliyo. Kude kudala kwimihla yoomatshini abafana nePorsche 930 Turbo okanye iFerrari F40, apho “yayingeyonto, yayingeyonto, yayingeyonto… TUUUUUUDO!” — ingekuko ukuba abanqweneleki kangako ngenxa yoko...
